ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 614,325, dated November 15, 1898. Application filed April 1, 1897. Renewed September 24, 1898. Serial No. 691,830. (No model.)

To a whom it may concern.-

Be it known that I, SIGMUND V.HUBER,a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented or discovered certain new and useful Improvements in Rolling- Mills, of which improvements the following is a specification.

The invention described herein relates to certain improvements in that class or kind of rolling-mill feed-tables forming the subjectmatter of an application, Serial N 0. 617,329, filed by me December 29, 1896. Such table consists of a construction and arrangement of feeding devices whereby a series of three, five, or more articles may be simultaneously fed, some in one direction and some in the opposite direction, through the reducingpasses of a three-high mill.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of a mill embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse section, the plane of section being indicated by the line III III, Fig. 2. Figs. 4, 5, and 6 are similar views, the planes of section being indicated, respectively, by the lines IV IV, V V, and VI VI of Fig. 2. Fig. 7 is a view similar to Fig. '6, illustrating a modification in the manner of driving the upper feed-rollers. Fig. 8 is a plan view showin g the lower feed-rollers of the catchers table positively driven. Fig. 9 is a sectional elevation showing a mill having four passes and illustrating a means for driving the upper feed-rollers. 1

In the practice of my invention I employ a three-high mill whose rolls are so constructed that the first, third, and fifth passes would be between the middle and lower rolls. On opposite sides of such a three-high mill are arranged the rollers table A and the catchers table B. These tables are formed by suitable side frames 1, provided with suitable bearings for the shafts 2 and 2 of the lower rollers 3 and 3". In each table these rollers are spaced a suitable distance apart, proportioned to the length of the article to be operated on, and the spaces between adjacent rollers are filled by plates or aprons 4. and 4!. As the rollers 3 are employed for feeding the article into the passes between the lower and middle rolls they are positively driven by a shaft 5, having keyed thereon beveled gears 6, adapted to intermesh with correspondinglyshaped pinions 7* on the shafts 2. The rollers 3 may be formed integral with each other, as clearly shown in Fig. 3, or may consist of three or more independent cylinders, as shown in Figs. 1 and 5. As the rollers 3 serve principally as antifriction-supports for the articles as they are fed onto the catchers table,

they need not be positively driven, but may be, as clearly shown in Fig. 8, by means of bevel-pinions 6 and 7 keyed,respectively,on the driving-shaft 5 and the roller-shaft 2. As indicated by the arrows, the first, third, and fifth passes of rollers table A are feed-passest'. e., the article is fed from them through rolls--while the first, third, and fifth passes of the catchers table are receiving-passes into which the article moves as it emerges from the rolls. From the receivingasses of the catchers table the articles are raised and laterally shifted to the feed-passes of said table, said passes being second and fourth in the series; from the second and fourth passes, between the upper and middle rolls, and thence into the second andfourth receiving-passes of the rollers table, and are then shifted by a suitable transfer mechanism to the third and fifth passes of the rollers table. As shown in Fig. 1, the upper passes of each table are arranged in vertical planes on opposite sides of the middle passes of the lower feed-rollers. In order to form these passes, suitable posts or standards 8 and S are secured to the framework of the feed-tables, and on these standards are supported channel-bars 9 and 9, which form the passes. These channel-bars have their webs or bottom portions slotted at suitable intervals, so as to permit the feed-rollers 10 and 10" to project a slight distance into the passes. As these upper passes in the rollers table are receiving-passes, the rollers 10 are mounted loosely in suitable bearings secured to the channel plates. As the rollers 10 in the catchers table are required to feed the articles into the reducing-rolls, they are driven either positively or fractionally by plain or toothed wheels 11 on shafts 12, mounted in suitable bearings in the sides of the frames of the tables and have beveled pinions keyed to one end thereof and adapted to intermesh with corresponding pinions on the driven shaft 5*, as clearly shown in Figs. 6 and 7. If desired, the rollers 10 may also be positively driven in the same manner as the rollers 10 but such construction is not generally necessary, as the reducing-rolls will serve to feed the articles into the second and fourth passes of the rollers table.

It will be observed that the rollers of the lower passes are idlers, or, if driven, mechanism independent of that employed for driving the upper rollers (when driven) is used. This independent driving of the rollers forming the upper and lower series is a characteristic difference from the construction shown in the application hereinbefore referred to and is decidedly advantageous as affording means for properly proportioning the speeds of the different series of rollers in accordance with the requirements of the work being done.

In order to transfer the article being rolled from the second to the third and from the fourth to the fifth passes of the rollers table and from the first to the second and from the third to the fourth passes of the catchers table, any suitable form or construction of transfer mechanism capable of vertical and lateral movement may be employedsuch, for example, as that shown in Figs. 1, 2, and 4. As clearly shown in Fig. 4, this transfer mechanism consists of heads 16 16, provided with upwardly-projecting prongs 17, which are secured upon the upper end of a vertically-movable standard 18, which is arranged in suitable guides secured to a transverse beam of the frame 19. The number of these lifting devices employed is dependent upon the length and thickness or rigidity of the article operated on. The longer and thinner the article the greater the number of lifters which should be employed. The frame 19 is made of such a length compared with the length of the feedtables as will accommodate the required number of lifters, and the transverse beams supporting the guides 18 of the lifters are arranged at suitable intervals along the frame 19. At suitable intervals the side bars of the frame 19 are provided with laterally-projecting lugs 20, whose outer ends are suitably shaped to form bearings for the wheels 21, which are supported upon rails 22, arranged transversely of the feed tables, below the rollers 3 thereof. As shown in Figs. 1 and 4, the frame 19 is connected by rods 23 to crank-arms 24, secured upon a shaft 25, which preferably extends the entire length of the mill. The shaft 25 is rotated to shift the frame 19 through the mechanism described by means of a fluid-pressure engine 26, having its piston-rod 27 connected by rods 28 to a crank-arm 29 on the shaft 25. In order to eifect the vertical movement of the standards 18 and the heads 16 16, shafts 29- are mounted in suitable bearings longitudinal of the frame 19, and on said shafts are secured the pinions 30, adapted to intermesh with rackbars 31 on the standards 18. It is preferred to form the standards with a vertical slot and to arrange the rack-bars on the inner walls thereof, as clearly shown in Fig. 4.

As shown in Figs. 1 and 2, these lifters are arranged to operate between adjacent feedrollers 3 and 3 and the heads 16 16 of such lifters are arranged a distance apart approximately equal to the distance between the second and fourth passes of the rollers table and the first and third passes of the catchers table. As will be seen by reference to Fig. 1, the lifting devices are arranged so as to transfer an article laterally from the second and fourth passes of the rollers table and downwardly to the third and fifth passes of the same table, whereas in the catchers table the lifters are arranged to lift the article from the first and third passes and move it later ally to the second and fourth passes.

In order to rotate the shafts 29, whereby the lifters are raised and lowered, pinions 32 are secured upon the shafts 29, and with said pinions the rack bar 33 intermeshes. This rack-bar is connected to the piston 34 of the fluid-pressure cylinder 35, which is movable mounted in guides 36, arranged upon a suitable foundation adjacent to the feed-tables. The fluid-pressure cylinder 35 is tied in suitable relation to the frame 19 so as to move therewith by means of rods 37, secured at their ends to the cylinder and frame 19, as clearly shown in Fig. 4.
